2 CAT 770-15 Introduction

Daikin HiLine™ fan-coil units The Daikin HiLine fan-coil air conditioning units are designed for use in multiple floor apartments, office buildings, hotels and other similar applications and require a minimum amount of floor space. Just one HiLine unit may do the job that formerly required more than one conventional unit .

The results of many years of experience in the development, design and manufacture of fan-coil air conditioners have been incorporated in the Daikin HiLine units to provide highly efficient, quiet performance; individual thermostatic control; simple, low cost installation; application flexibility; and low maintenance and operating costs with no sacrifice in room comfort, design, or appearance. For the ultimate in design, performance, efficiency, flexibility of application, and ease of installation and maintenance, look to Daikin HiLine fan-coils . Application flexibility Two distinct designs are available with the complete flexibility necessary for any application requirement. • Low cfm design - The 300 through 800 cfm blow- through configuration units are designed to meet individual room control requirements. • High cfm design - The 1000 and 1200 cfm draw-through configuration units are designed for multiple discharge arrangements so that one unit can serve more than one room . Both designs are available for two-pipe and four-pipe systems with single, double, triple and top discharge arrangements. Optional equipment is available to provide complete application flexibility.

Controls, valves, motor and fan assembly are accessible by removing the access panel. Knock-down unit The FHSK knock-down unit configuration, available for unit sizes 03 through 08, allows installation, leak testing and insulation of the risers and stub-outs prior to the unit placement. Risers can be field provided or factory supplied Plug-in Field Mounted Thermostat and shipped to the jobsite before the units . After riser installation, the bottom half of the unit is set in place. Connections are then made to the supply, return and drain risers as well as the power supply. Then the top half of the unit is installed . Fast, low-cost installation Installation time is minimized by the unit’s design, riser slip couplings, and unit mounted controls. Units are completely factory assembled and wired and have individual thermostat controls. Risers are factory cut to 104" in length and insulated. Optional riser couplings are available. Installation is accomplished by simply stacking the units one above the other floor-by-floor, brazing the couplings and risers together, and connecting the power. Only one person is required for installation because the slip couplings eliminate the requirement for perfect unit alignment with the swaged riser joints of other manufacturers . Twin units To reduce installed cost, two units of opposite hand on each floor can share a set of supply, return and drain risers. Individual thermostat control is retained by each unit. Units can be placed side-to-side, or side-to-back

Thus, a Figure 1: Reverse Return Piping System 200 ft. length would expand approximately 1" each way. Another method is anchoring the riser pipes at the end and absorbing the expansion with an expansion compensator. If an expansion compensator is used, the pipe should be guided. In some situations, a combination of both methods may be required. The risers must be secured at some point as the units have not been designed to support the riser weight. Number of floors per riser The standard HiLine unit with service valves, expansion loops, etc., will operate at 250 PSI working pressure which is equivalent to a 35 to 40 story building.
